    Synthetic Oil

    Ducati's "desmodromic" valve system. The engine's valves are opened AND closed by cam followers. There is only a very weak valve spring on those. Valve lash is set by hand lapping the cam followers. The older two valve Desmo engines could have the valve clearances set relatively easily. The...

    Synthetic Oil

    Doing this will bypass the "heating" of the ATF, and will not generate any codes, as the coolant circuit thru the 3-way valve will remain intact. The TBV, transmission bypass valve which is located inside a manifold behind the heater unit, will still keep ATF from flowing to and thru the trans...

    Why on Earth do people want to disable MDS? (Hemi newb here)

    "Normal" fuel mileage depends on what one's definition of "normal" driving is. Easy driving on the rural roads around here I routinely see 18-19 mpg on the Lie-o-meter. In stop and go in town, that will drop to the 15-16 range easily; less if I drive more aggressively like rabbit starts and...

    Synthetic Oil

    When I had my 2012 Boss 302, I first ran the MC 5W-50. After a LOT of online research found that the MC 5W-50 sheared down to a 30 weight in less than 1000 miles in the 5.0 motor. After I installed a trio of gauges on the car, including an oil pressure gauge, morning start up pressure was well...

    Synthetic Oil

    Good jest gents but after living in Germany for 12 years while stationed there when on active duty, one really gets used to doing things "metrically" (if thats even a word). The Metric system just makes sense. It took me a bit to reacquaint myself with the damn English/US system after my last...

    Engine oil temp?

    Good pic. looks as if FCA changed the calibration on the TBV for the 8-speed on the '19 MY trucks as your trans temp is at 170 degrees. If I took my '17 on an ~15 mile (assumed) round trip in similar temperatures, my trans temp would be at or close to 185 degrees depending on how hard or fast...

    Engine oil temp?

    I believe tho, the A8 cars have some kind of thermostatic valve plumbed in the trans cooler lines, at least I've seen what looks like one in diagrams of ATF lines for those vehicles. I do know that diesel Rams have a thermostatic valve plumbed into the ATF lines running to and from their trans...

    Engine oil temp?

    Here is a pic of the bore in the aluminum manifold the TBV fits in. The cast tube leading to the top of the pic carries ATF to the trans cooler lines and to the cooler when the TBV opens.

    Engine oil temp?

    In the FYI category, here is a pic of the TBV removed from it's bore in the aluminum manifold which is bolted to the back of the trans heater assembly. The black plastic cap is at the bottom. The TBV just pulls off of the plastic cap.

    Engine oil temp?

    Actually thats not entirely true. I acquired a complete trans heater assembly from a wrecked vehicle and looked at the TBV. It's held into it's bore by an internal snap ring on a plastic, o-ringed cap. The snap ring can be removed, the cap and TBV pulled from it's bore, and the TBV removed...

    Engine oil temp?

    Thats interesting. Never saw that with mine. I tow a max 3500# GW enclosed cargo trailer, and whether pulling that (empty or loaded), or with no trailer, my 8-speed temps sit at 185/186 degrees when driving normally. When accelerating up a long incline (tho nothing remotely close to the Ike)...

    Synthetic Oil

    Perhaps. I also own an Armalite AR10 and love it. The LMT weapons are made to withstand years of military use, and the 7.62 version was produced in response to an RFP from the UK military, a contract they won. LMT is based in Ohio I believe, so it's a win for the US. Overspec'd no doubt, but...

    L129A1. I misquoted the price: $5999.95. This is as close as you can get to the weapon provided to the UK military. One hell of a weapon, but then so is the price. 7.62X51 SPECS Model L129A1 Reference Rifle With Accessories Caliber 7.62x51 Operating Method Direct Impingement Barrel 16...

    Synthetic Oil

    In a firefight, my choice of weapon would be an LMT (Lewis Machine Tool) 7.62 AR carbine. That weapon was selected by the SAS as their weapon of choice. Unfortunately those babies cost in the $3500 ea range, which is a tad more than I would prefer to spend for a rifle.

    Have a Marlin Guide gun in 45-70. More than a few rounds at the range without a good recoil pad will leave a sore shoulder, and thats shooting only the standard 300 grain rounds. Try shooing one of Garretts 540 grain "Hammerheads", (safe ONLY in a Marlin lever action), and you will have a whole...

    Poll- Would you buy a Ram again??

    Interesting question. This is my third Ram, the first two were diesel heavy duties. When this truck, 2017 1500 Limited, is worn out it will depend what is being offered by Ram and it's competition. I can say there is no way I will go near a GM product, even at gunpoint. Owned two previously...

    Even the 2012 Boss 302 I had came with a flexible hose that connected the passenger compartment with the engine intake duct to "pipe" in that sound. Was the first thing I removed completely. After installing a 3" Magnaflow cat back with true X-pipe and what they called mid=range "mufflers"...

    Synthetic Oil

    Grew up in a family which was Mopar specific, so as I began driving naturally gravitated that way. The FCA of today is not the Mopar of the 60's, and early 70's unfortunately. All the premier engineering talent is long gone. Just do a bit of research on v8 engines and which ones, from the...

    25 degrees and you are changing oil in the dark outside; sounds like me in my younger days. Good on ya!

    Sold the truck

    Turbochargers are a consumable item. Every turbo will eventually wear out and fail. Turbo's on diesel trucks can last a million miles primarily due to the lower exhaust temperatures of diesels compared to gasoline engines, but they can fail if abused too. Despite water cooling, and whatever a...

    Is it safe to disable MDS on a regular basis?

    For what it's worth, I religiously turn the MDS off every time I get in the truck using the toggles. Have been doing that for just about all of the 28K miles on the truck so far. No issues, and no "ECO" light. The very few times I've forgotten to turn the MDS off, I'm quickly reminded that I...

    Synthetic Oil

    Since I had a 2012 Boss 302 for 5 years (until sold), a few comments; I ran the Motorcraft 5W-50 for one OCI, switched to Schaeffers 5W-50 for three more before settling on Amsoil SS 10W-30, which I ran until the vehicle was sold. The Coyote 5.0 developed very high oil pressure on start-up...

    Synthetic Oil

    Have to believe that a large part of this problem is the fact that those engines have an "open deck" configuration. Meaning that the cylinders are NOT supported by ANY block material for more than a few centimeters below the deck surface. The ONLY thing stabilizing the cylinders is the...

    Synthetic Oil

    Couple of things come to mind; first, I don't believe the HD trucks fall under the CAFE rules, though I could be wrong on this. But if so, an oil viscosity was specified that would maximize engine protection (0W-40). Second, the HD trucks are "assumed" to be used more often for work, ie...

    Oil Filter struggle and remote filter kit install

    Just a word of caution, in the for what it's worth department. I installed the perma-cool kit about a year ago on my 2017. One morning after starting the truck, the oil pressure went to ZERO and I quickly shut it down. One of the hoses clamped to the engine adaptor had blown right off of the...
